/**
  This class implements an inspector for GoJS model data objects.
  The constructor takes three arguments:
    {string} divid a string referencing the HTML ID of the to-be inspector's div.
    {Diagram} diagram a reference to a GoJS Diagram.
    {Object} options An optional JS Object describing options for the inspector.
 
  Options:
    inspectSelection {boolean} Default true, whether to automatically show and populate the Inspector
                               with the currently selected Diagram Part. If set to false, the inspector won't show anything
                               until you call Inspector.inspectObject(object) with a Part or JavaScript object as the argument.
    includesOwnProperties {boolean} Default true, whether to list all properties currently on the inspected data object.
    properties {Object} An object of string:Object pairs representing propertyName:propertyOptions.
                        Can be used to include or exclude additional properties.
    propertyModified function(propertyName, newValue) a callback
 
  Options for properties:
    show: {boolean|function} a boolean value to show or hide the property from the inspector, or a predicate function to show conditionally.
    readOnly: {boolean|function} whether or not the property is read-only
    type: {string} a string describing the data type. Supported values: "string|number|color|boolean" Not yet implemented: "point|rect|size"
    defaultValue: {*} a default value for the property. Defaults to the empty string.
 
  Example usage of Inspector:
 
  var inspector = new Inspector("myInspector", myDiagram,
    {
      includesOwnProperties: false,
      properties: {
        "key": { readOnly: true, show: Inspector.showIfPresent },
        "comments": { show: Inspector.showIfNode  },
        "LinkComments": { show: Inspector.showIfLink },
      }
    });
 
  This is the basic HTML Structure that the Inspector creates within the given DIV element:
 
  <div id="divid" class="inspector">
    <tr>
      <td>propertyName</td>
      <td><input value=propertyValue /></td>
    </tr>
    ...
  </div>

  DebugInspector code
  Two classes: DebugInspector and View
  An DebugInspector is a collection of Views
 
  Each property corresponds to its own View.
  Each View correspondingly has its own DOM elements.
  Views are also responsible for populating those DOM elements
  and committing information from them, when requested.
  Right now Views have three essential settable functions:
    initialize = Creates DOM. Called once.
    populate = Fills DOM, ie input.value = some value. Called each time the DebugInspector asks.
    use = Returns a value or values from the View's DOM inputs. DebugInspector solicits this when it wants to commit some values.
 
  The inspector adds the DOM elements of all Views to its master div (this.div), plus an accept button (or not).
 
  Finally the inspector has a collection of objects to inspect.
  For now this is only ever a single object.
 
  When the collection changes, the inspector passes on information
  to all of its Views so that they may re-populate their inputs.
